Well I got the Omega 8000 and with the weather finally clear, I expect to get out this afternoon for a maiden run at one of the local schools. Now let's see if I have this setup correctly. Turn on, find clear spot (by pressing pin point in disc mode or leave in at) set disc to 16 (to knock out small nails) or maybe higher if in heavy trash. set sens. as high as noise allows. Use 3 or 4 tones and use freq shift if experiencing interference... Does that sound about right? Thanks for any advice....
